Telomeres in cancer cells exposed to oxidative stress got shorter and stickier.

When hair follicle stem cells lose their protein-based death cue, they take on a new role helping to repair wounds in skin.

Internalizing the environment might be the next step in humans’ relationship with our planet.

Apoptosis and other types of programmed cell death appear to be reversible.

Molecular programs can rescue cells already engaged in the process of apoptosis or other forms of programmed cell death.

The biologist earned a Nobel Prize in 2002 for his work on C. elegans.

M proteins from Streptococcus bacteria selectively kill mouse macrophages and human macrophage-like cells by prompting cell death.

The immune cells—known for clearing dead cells—also chew up live progenitors in neurogenic regions of mouse brains. 

A decade of research on intercellular mitochondrial transfer has answered some long-standing questions and raised new ones.
